Though fire crews initially said they "may not be able to save Notre Dame," they were able to preserve the main structure including the outer walls and the two bell towers. Photos from inside the cathedral taken Tuesday morning showed debris still smoldering around the altar. On Tuesday, a tweet surfaced showing the rooster from the iconic spire survived the fire.

People in France and around the world were in mourning over the damage, including the loss of the building's iconic spire and part of the roof. Artifacts and artwork in the cathedral were saved by Parisian fire services and the city's deputy mayor for tourism and sports, Jean-Francois Martins, and his team. They were able to salvage the Crown of Thorns, the Blessed Sacrament and other items. The rescued works were transported to the Louvre Museum for safekeeping.
